Relative positioning system method
First Claim
1. A relative positioning system comprising:
- an adjoining pair of spaced apart receivers positioned proximal to an object causing a signal interference with a radio frequency signal detectable by each receiver of the adjoining pair, the radio frequency signal associated with an emitter; and
control electronics operatively coupling the spaced apart receivers, the control electronics configured to determine a direction of the emitter based on the signal interference.

Abstract
A relative positioning system and method has an adjoining pair of spaced apart receivers positioned proximal to an object causing a signal interference with a radio frequency signal detectable by each receiver of the adjoining pair. The radio frequency signal is associated with an emitter. Control electronics operatively couple the spaced apart receivers. The control electronics are configured to determine a direction of the emitter based on the signal interference. In an embodiment of the system and method the emitter is associated with an object of interest, the signal encodes information relating to the identity and status of the object, and information and heading of the object are cutaneously communicated to an operator by an article worn by the operator.

4. A relative positioning system for determining a heading of an object emitting a signal having a signal strength, the system comprising:
-
a plurality of receivers, each receiver able to receive the signal from the object; a two-dimensional, body-centered coordinate system formed by the plurality of receivers; and control electronics operatively coupling the plurality of receivers, the control electronics being configured to produce a directional cue corresponding to the heading of the object based on the strength of the signal received by each of the plurality of receivers. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14)
